Shore

Abstract

Disclosed is a shore which has a durability with respect to loads not only in a longitudinal direction and a lateral direction but also in a lengthwise direction, and which can be automatically folded without requiring extra work. The shore comprising a pair of front and rear fixed frames 10, a pair of left and right foldable reinforcing frames 11 interposed between both left and right ends of each of the fixed frames, and a pair of front and rear floor plates 12 whose proximal ends are pivotally mounted to an inner intermediate portion of each of the fixed frames, characterized in that said reinforcing frame comprises a folding handrail column 13 whose proximal end is pivotally mounted between upper ends of the fixed frame, four expandable braces 14 whose proximal ends are pivotally mounted to upper and lower ends of each of the fixed frames and obliquely extending toward the inner intermediate portion, a support member 15 comprising a flange 16 for pivotally mounting an extreme end of each brace 14 and a guide tube 17 provided on the back surface of the flange, a support rod 18 whose proximal end is secured to the intermediate portion of said handrail column 13 and whose lower end is secured into or slidably and selectively inserted into said guide tube, and a bracket 19 provided at the lower end of said support rod and for rotatably connecting the extreme end of said floor plates.
